Spiral Wound Gasket With Outer Ring By Antileak Seal Ltd.

We provide Spiral Wound Gasket with Outer Ring to prevent gasket blowout and acts as a compression stop.. Antileak GA 01102 Spiral Wound Gasket with outer ring is also called SWG with centering ring. It is the most common profile of spiral wound gasket and used extensively in ANSI B16.5 flanges. The gaskets consist of a metal guide ring and the basic SWG sealing part. The external ring accurately centers gasket on flange face, provides additional radial strength to prevent gasket blowout and acts as a compression stop. This profile is normally used in raised and flat faced flange. The outer ring is often made of carbon steel (painted or zinc plated to prevent corrosion) but can be made of alloys for higher temperature and more severe medium applications.
